Seiko SNKK87 Watch Review

Seiko SNKK87 Dial & Case Design

Like a lot of the SNK series, this model has a simple yet effective dial design with an easy to read finish. The hands and hour markers are coated in lume which also makes them easier to see in dim lit conditions. The day and date display at the 3 o’clock position can also come in useful.

The casing is made of a strong stainless steel and features an exhibition glass caseback to let you view the movement of the watch.

Seiko SNKK87 Type Of Crystal

The Seiko SNKK87 features a proprietary Hardlex crystal that’s stronger than traditional mineral crystal glass. It’s found in many of Seiko’s watches and gives you good protection from scratches and knocks.

Seiko SNKK87 Watch Movement

Powering the watch is the popular Seiko 7S26 21 jewel automatic movement. The movement beats at 21,600 BPH giving it a smooth 6 ticks per second that looks good. The movement has a 43 hour power reserve and doesn’t feature hacking or manual winding.

Seiko SNKK87 Watch Size

The Seiko SNKK87K1 has a casing diameter of 38mm not including the crown. The thickness of this casing is approximately 12mm. Overall a decent size for those of you out there who prefer medium – small watches.

Seiko SNKK87 Strap

The strap on this timepiece is made from stainless steel and has a 20mm width. If you want to you can swap out the strap as it is replaceable. It fastens with a fold over push button release clasp.

Seiko SNKK87K1 Extra Features

One of my favourite extra features of this watch is the exhibition caseback which lets you take a peek at the inner workings of the timepiece and its automatic movement.
